New crash information added by DrKonqi

rekonq (0.9.1) on KDE Platform 4.8.2 (4.8.2) using Qt 4.8.1

- What I was doing when the application crashed:
 surfing my account on www.amazon.it 
"suggests > improve this suggest" opens a new tab, on this tab when clicking on the link "close this window" rekonq crashes
.
